Silicone O-ring 20.3X2.4 O-ring VMQ / MVQ

High-Temperature Silicone Sealing Solution

VMQ / MVQ Material Properties and Performance

Technical Dimensions and Industrial Use

Main Description:
The Silicone O-ring 20.3x2.4 VMQ / MVQ is a precision elastomer sealing element designed for static and low-pressure dynamic applications. Manufactured from high-quality VMQ (MVQ) silicone rubber, this O-ring provides excellent flexibility, thermal stability and long-term sealing reliability across a wide temperature range.

With an internal diameter of 20.3 mm and a cross-section thickness of 2.4 mm, this silicone O-ring ensures accurate fitment in standard grooves and housings. VMQ material is widely used in industrial sealing systems due to its resistance to extreme temperatures, ozone, UV exposure and aging. Compared to NBR-based seals, silicone O-rings perform significantly better in high-temperature environments and applications requiring long-term elasticity.

The 20.3x2.4 O-ring is suitable for industrial machinery, pneumatic systems, food-processing equipment and light chemical environments where flexibility and temperature resistance are essential. It functions as a reliable technical seal in housings, flanges and cover assemblies, preventing leakage of air, water and compatible fluids.

Thanks to its smooth surface finish and consistent cross-section geometry, the silicone O-ring ensures uniform compression and effective sealing performance. It can be installed in standard metric grooves and integrated into a wide range of industrial assemblies.

For B2B customers, this VMQ / MVQ O-ring represents predictable sealing performance, reduced maintenance requirements and dependable operation in demanding environmental conditions.

FAQ

1. What does VMQ / MVQ mean in silicone O-rings?
VMQ and MVQ refer to silicone rubber compounds known for high temperature resistance and flexibility.

2. What temperature range can silicone O-rings handle?
Silicone O-rings typically operate in a wide temperature range, often from around -60°C to +200°C, depending on formulation.

3. Is silicone resistant to oils and fuels?
Silicone has moderate resistance to some oils but is not recommended for continuous contact with fuels or petroleum-based fluids. For oil-heavy environments, NBR or FKM may be more suitable.

4. Where is a 20.3x2.4 silicone O-ring commonly used?
It is commonly used in pneumatic systems, food-processing equipment and high-temperature industrial applications.

5. Is this O-ring suitable for dynamic applications?
It is mainly recommended for static sealing or low-speed dynamic applications due to silicone’s lower abrasion resistance compared to other elastomers.
